Which page has the "throw new Error"? I am not seeing it

[KiwiKilian]

Sorry, I screwed up on the link. I've updated it, it's still present with the current version. The error is withing src/routes/__root.tsx.

next step is creating a failing e2e test as a PR

PR with failing E2E test is up #4862.

we now ignore errors thrown from head, which also means you cannot throw a redirect from head. if you need to throw a redirect, throw it from beforeLoad or loader
